Abstract

PROCEDIMIENTO PARA LA PRODUCCION DE UN POLIMALEATO CON UN PESO MOLECULAR COMPRENDIDO ENTRE 300 Y 5.000.CONSISTE EN HACER REACCIONAR ACIDO MALEICO O ANHIDRIDO MALEICO CON UN HIDROXIDO METALICO O HIDROXIDO AMONICO EN MEDIO ACUOSO, EN CANTIDADES EQUIMOLECULARES O EN UN EXCESO DEL 10, CON UN PH COMPRENDIDO ENTRE 3,5 Y 5, PARA OBTENER UNA SOLUCION ACUOSA DE UN MALEATO MONOMETALICO ALCALINO O MONOAMONICO. EL MALEATO OBTENIDO SE POLIMERIZA CON O SIN AISLAMIENTO DEL MEDIO ACUOSO EN EL QUE SE HA PRODUCIDO, A UNA TEMPERATURA COMPRENDIDA ENTRE 80 Y 180 GRADOS Y EN PRESENCIA DE UN INICIADOR DE LA POLIMERIZACION EN UN DISOLVENTE ACUOSO.
